Answer:
a) Wet ear waxed father
b) Wet ear waxed mother
Explanation:
Having wet earwax is a dominant trait in humans , represented by "W"
Having dry earwax is a recessive trait in humans , represented by "w"
When a dominant and recessive trait occur together, only the trait associated with the dominant allele is expressed.
Now a cross is being carried between two parents having following genotype
Father - "WW"
Mother - "Ww"
a) The fathers phenotype would be "wet earwax" as both the alleles "W" are dominant allele and thus father is a "dominant wet ear waxed homozygous father"
b) The phenotype of mother is "Wet earwax" as when a dominant and recessive trait occur together, only the trait associated with the dominant allele is expressed. Thus, mother is a "wet ear waxed heterogyzous mother"
